Samuel manufactures a single product. Total cost per unit is $70 when production is 100 unitsper week, and $62.50 when production is 160 units per week.What are the total fixed costs per week?A $450 B $750 C $1200 D $2000

To find the total fixed costs per week, we need to determine the difference in total costs between the two production levels and isolate the fixed costs.

Step 1: Calculate the difference in total costs: Total cost at 100 units per week = $70 per unit * 100 units =$7000 Total cost at 160 units per week = $62.50 per unit * 160 units =$10000

Step 2: Find the difference in total costs: Difference in total costs = Total cost at 160 units per week - Total cost at 100 units per week Difference in total costs = $10000 -$7000 = $3000

Step 3: Identify the fixed costs: Fixed costs = Difference in total costs - Variable costs Fixed costs = $3000 - ($62.50 per unit * 160 units) Fixed costs = $3000 -$10000 Fixed costs = -$7000

Since the result is negative, it means there are no fixed costs. Therefore, the correct answer is option A) $450.
